Robert Taylor, general manager of the New Tardebigge on Hewell Lane, said: “We’ve been a top choice for birthday parties over the years, so what better way to celebrate our own big birthday than by hosting the world’s biggest party.

"We’re planning a bumper load of fun and games and it’s all for free, so I’d urge local parents to register now to ensure their kids don’t miss out what is sure to be the biggest and best kids’ party of all time.”

The world’s first Wacky Warehouse opened in 1994, as a place for kids to have fun and at the same time enjoy a family meal with their parents at the adjoining pub.

Since then Wacky Warehouse has opened 78 outlets nationwide, becoming the UK’s largest soft play and activity centre for children aged up to 12-years-old, hosting more than 400,000 kids’ parties in the process.

As well as free entry into the world’s biggest party, five lucky youngsters will also receive a limited edition Wacky Platinum Card, which entitles them to unlimited free entry to Wacky Warehouses across the UK up until their 12th birthday.
